The proposed circuit is based on a « Flyback » type architecture, incorporating the self-starting principle of the power switch control circuit. This topology has a high voltage conversion ratio between the input voltage and the output voltage.
The proposed architecture guarantees a supply voltage of 24 VDC with a variable output power of 1W up to 20W, from an input voltage of up to 2kVDC. An evolution of the design could be studied in the case where different levels of input voltage or output power would be needed.
